The GeForce GTX 1070 Ti is NVIDIA’s latest HD and VR ready, gaming GPU and is successor to the current number one GPU by market share, the GTX 1070. Like the 1070, the 1070 Ti is based on the16nm Pascal architecture and GP104 GPU. Both feature 8 GB of GDDR5 memory with a 256 bit memory interface producing a total memory bandwidth of 256 GB/s, and both have a rated boost clock speed of 1.683 GHz, although both are geared to be over clocked. In fact, the 1070 Ti is basically the 1070 but with 25% more working CUDA cores (2432 versus 1920) and slightly higher base clock of 1607MHz (versus 1506MHz in the 1070). This translates to the 1070 Ti being as nearly as powerful as the GTX 1080 which has 2560 CUDA cores, 8 GB of GDRR5X memory and boost clock of 1733 GHz. With founder’s editions available at $449, compared to $470 for AMD’s recent Vega based RX 56 and $510 for the GTX 1080, the 1070 Ti represents good value for money. The rumoured fast approaching release of Volta (NVIDIA’s next generation architecture following on from Pascal) in early 2018 may upset demand for the 1070 Ti. [Nov '17GPUPro]

The AMD R9 380 succeeds the Tonga based R9 285. The only difference between the two cards is a tiny 2% GPU clock increase on the R9 380 but for the most part, the R9 380 is identical to the R9 285. We only have one sample of the R9 380 so far and comparing benchmarks between the R9 380 and R9 285 shows that the two cards are indeed very close. Unlike with several of the other AMD R9 300 series re-badges, the MSRP has actually dropped on the R9 380 to $199. This card could be a strong value contender if prices drop much below $200.
